15. Suppressing MTU2–MTU2S Synchronous Counter Clearing
Figure 10.62 MTU2–MTU2S Synchronous Clearing-Suppressed Interval Specified by SCC
TGRA_3
TGRB_3
In the MTU2S, setting the SCC bit in TWCR to 1 suppresses synchronous counter clearing
caused by the MTU2.
Synchronous counter clearing is suppressed only within the interval shown in figure 10.62.
When using this function, the MTU2S should be set to complementary PWM mode.
For details of synchronous clearing caused by the MTU2, refer to the description about
MTU2S counter clearing caused by MTU2 flag setting source (MTU2-MTU2S synchronous
counter clearing) in section 10.4.10, MTU2–MTU2S Synchronous Operation.
